History WesternAnimation / YoungJusticeRevivalSeries

* AnAesop: There is a very clear cut message about playing shadow politics throughout the season. Keeping secrets and manipulating others is ''not'' acceptable and should not be done, regardless of intentions or motives. You may move your goals forward and may even come out ahead for a bit, but using illicit methods to make gains ''will'' catch up with you and sooner or later you ''will'' be made to answer for your actions. The heroes barely avoid self-destructing because of their chosen methods and the villains start taking heavy hits like never before because of theirs.

* LastEpisodeNewCharacter: [[spoiler:[[ComicBook/{{Supergirl}} Kara Zor-El]]]]

** The Team enters the Phantom Zone to [[spoiler:rescue Superboy who has been trapped there for months]] but are ambushed and defeated by the criminal Kryptonians that reside there. Planning for this, Nightwing breaks out a piece of kryptonite to weaken them, but being in the Phantom zone means it doesn't affect them physically and it gets taken by Dru-Zod, the Kryptonian leader. Later Dru-Zod uses the same piece of kryptonite to incapacitate Superman once they get out of the Phantom Zone.

** On a team level, there's the Outsiders this season being led and founded by Nightwing, while Batman starts his own organization called Batman Incorporated. In the comics, the original Outsiders were formed by Batman himself, largely for the same reasons (being dissatisfied with the League), but here it's instead a team taken from ''ComicBook/BatmanGrantMorrison'', which draws from that team with new additions to fit the storytelling similar to Nightwing's Outsiders. Basically, the idea of the Outsiders was split in two.

** ''Phantoms'' has Batman appear only briefly with no lines sporadically throughout the season, with other older league members like Martian Manhunter, Zatara, Orin Aquaman, Jay Garrick, and Superman having more substantial roles in his place.

* OneWheeledWonder: In "Royal We," Artemis rides a one-wheeled motorcycle on the covert mission to Markovia. SHe abandons it unpon rescuing Halo, as the bike is too small for both of them.
* PoisonousPerson: both the first and second Plasmus were metahuman teens turned into monsters that were so dangerous that touching them would cause your skin to melt.

* DoubleEntendre: Shortly after they get engaged, we see Superboy and Miss Martian at home together, with Miss Martian out of sight in another room. Superboy asks her what she's doing, and she replies "Wearing my engagement ring. That's all." Superboy almost immediately realizes that while it ''sounds'' like she means she's admiring the ring, it can also mean that the ring is the ''only'' thing [[ReadyForLovemaking she's wearing]]. He rushes into the other room, and we hear her giggle happily.

** Then in ''Phantoms'', after a lot of criticism towards his run as King of Atlantis, Orin ends up passing the crown (after a tulmultuous arc) to [[spoiler:Mera]].

** Although it's been around since earlier seasons, there's the recurring gag that [[PropRecycling a school bus with exactly the same driver and crew]] is always needing saving. Zatanna's arc calls attention to this by having the bus ''appear in space'', [[TheStinger go through alternate dimensions in the credits]], and eventually revealed that it was all intentional: Klarion was using the bus as a temporary anchor to travel through time, and the Team makes use of it [[spoiler:because it was able to enter the Phantom Zone]].

* RewatchBonus: [[spoiler:Superboy was believed dead in the first place because an ash stain was left on the wall in the same place the bomb was destroyed in, and seemed to be contradictory to him actually being in the Phantom Zone. In reality, that's because the stains belonged to [[KarmicDeath Lor-Zod]], who made another attempt to kill him but had been set up by Metron to be abandoned in the blast of the bomb.]]

A fourth season with the subtitle of ''Phantoms'' was released in two halves, the first in October 2021 and the second half released in March 2022. ''Phantoms'' uses a mini-arc format (about 4 episodes) to tell its story. M'gann and Conner head to Mars, while Artemis deals with a situation regarding the League of Shadows. Zatanna is now teaching three young sorcerer and teams up with Doctor Fate to stop a new Lord of Chaos. Kaldur handles political instability in Atlantis. Rocket travels to New Genesis in an attempt to form an alliance with the New Gods. Nightwing's arc focuses on [[spoiler:trying to discover what happened to Superboy.]]

** Season 4 repeats the pattern with INVITATION TO [[KneelBeforeZod KNEEL BEFORE ZOD]].

* InnocentCohabitation: In Season 3, Artemis lives with her brother-in-law, Will--Roy-- Harper, and her niece, Lian, in Star City. (Her sister, Jade, has left for reasons [[AmbiguousSituation unknown]].) Potentially not completely [[ShipTease innocent]], if [[ShipperOnDeck others]] are to be believed, and if [[TheMatchmaker they]] got what they wanted. Still remains innocent, as far as we're shown.

* LightFireJuxtaposition: Continuing from the [[WesternAnimation/YoungJusticeOriginalSeries first two seasons' example]], ''Phantoms'' shows that Klarion and Dr. Fate's respective kindreds are visually distinguished by this trope when in their natural forms. The Lords of Order look like radiant, golden diamonds whilst the Lords of Chaos look like bloodred diamonds wreathed in flame.

* KryptoniteIsEverywhere: The TropeNamer is a subversion, as season 4 reveals the substance is quite rare in this show's canon, and the Justice League has tabs on all known samples. [[spoiler:The kryptonite sample that Lor-Zod uses in the bomb targeting Superboy is also explicitly stated to be the last known sample in his timeline.]]

'''Unmarked spoilers for [[WesternAnimation/YoungJustice the original series]] will follow.'''

* TenMinuteRetirement: Comicbook/BlackLightning does this at the beginning of the series, having killed a 14-year old girl. [[PowerIncontinence He also temporarily loses his ability because of this.]] However, Comicbook/{{Nightwing}} is able to convince him to go on one last mission. His ex-wife lampshades this trope, saying that giving up the life never sticks with superheroes.

** Nightwing's team in the first half of the season is a composite of multiple eras of the Outsiders team along with new additions: Black Lightning, Geo-Force and Halo are founding members of Batman's original Outsiders in 1983, while Nightwing was the founder of the 2003 reboot, here serving as the leader as well. Meanwhile, there's Comicbook/{{Superboy}}, Tigress, Oracle and Forager, who are new additions that were never affiliated in the comics.
** Comicbook/GreenArrow, Arrowette, Comicbook/PlasticMan, and Comicbook/{{Hardware|1993}} were never members of Batman Incorporated in the comics. Comicbook/{{Katana}} and Comicbook/{{Metamorpho}} were, but as part of a sub-team led by Tim Drake and otherwise comprising the original Outsiders.
** Beast Boy's Outsiders team bears little resemblance to any version of the comic team. The only common element they share is that both center on the theme of the members being 'outsiders' in some way, but each operates very differently. In terms of roster, Beast Boy's Outsiders is almost identical to the Johns' era Teen Titans, only absent Starfire, Raven, and Cyborg (who was later introduced and eventually joined as well), and with the addition of Comicbook/{{Static}}, Comicbook/BlueBeetle, and Geo-Force (the only actual member that was part of the Outsiders in the comic). Their purpose actually bears more in common with the Comicbook/DoomPatrol or Marvel's Comicbook/XMen, in that their primary goal is to better the image of super-powered indiviuals with the public.

** Unlike most adaptations of ''Comicbook/TheJudasContract'', Beast Boy and Terra have no romantic interest in each other, and the former is dating Queen Perdita.

** A villainous example with Ma'alefa'ak. Originally a minor antagonist in season 3 who was aligned with Apokolips and played a part in why Forager went to Earth, by season 4, he becomes one of the [[ArcVillain Arc Villains]] and works with the seasonal threats, the Zod family.

* BaitAndSwitch: After Lobo gets one of his fingers cut off, we [[IncrediblyLamePun cut]] to it multiple times throughout the season growing, implying that it may grow into Slobo. And then at the end of the season, [[spoiler:[[ShaggyDogStory Lobo stomps on it and burns the remains just as "Slobo" is "born".]] There can only be one main man...]]

** In season 3, the Light return, with Ra's Al Ghul, the Brain, and Black Manta being replaced by Characters/{{Deathstroke}}, [[EvilutionaryBiologist Ultra-Humanite]], and [[spoiler:[[EvilOldFolks Granny Goodness]] (serving as Darkseid's proxy)]]. "[[Recap/YoungJusticeS3E7Evolution Evolution]]" reveals that [[spoiler:Comicbook/{{Darkseid}}]] and [[DiabolicalMastermind Vandal]] [[TheSocialDarwinist Savage]] made a pact centuries ago to conquer the galaxy together, and once complete, Apokolips and Earth would fight each other in one final "winner take all" battle.

** "[[Recap/YoungJusticeS3E9HomeFires Home Fires]]" features appearances from the families of several League members, including the first appearance of Comicbook/LoisLane.

** On a team level, there's the Outsiders this season being led and founded by Nightwing, while Batman starts his own organization called Batman Incorporated. In the comics, the original Outsiders were formed by Batman himself, largely for the same reasons (being dissatisfied with the League), but here it's instead a team taken from ComicBook/GrantMorrisonsBatman, which draws from that team with new additions to fit the storytelling similar to Nightwing's Outsiders. Basically, the idea of the Outsiders was split in two.

** Also out of focus are Comicbook/WonderGirl, Static, and El Dorado (Eduardo Dorado Jr.), even though they're members of the Outsiders as well. So far, they've only appeared in fights, though Eduardo did receive focus in regards to the Meta-Human Youth Center in Taos, but whenever the Outsiders are merely hanging out, it's usually just Forager, Cyborg, Halo, Brion, Terra, and Garfield, who are the residents of The Hub in the Premiere Building.

** Several of the adult mentors from the first two seasons, most notably Comicbook/RedTornado and Comicbook/MartianManhunter, also hardly show up.

* MythologyGag: Around the not-yet-Cyborg Victor Stone. His dad ''and'' one of his football teammates (named Ronnie, a reference to Cyborg's EvilCounterpart Ron Evers) are played by Khary Payton, who voiced him in Teen Titans among several other works; he's ''constantly surrounded'' by his most familiar voice. And his catchphrase; we get plenty of "booyah" from the football team, including Ronnie. Finally, his jacket is basically his costume from Series/{{Smallville}}.

* PassingTheTorch: King Orin has retired from being Comicbook/{{Aquaman}} (and the Justice League) to focus on being king, passing the mantle to Kaldur.

* PuttingTheBandBackTogether: “Terminus” reunites the five surviving members of the Season 1 team (not counting Comicbook/{{Zatanna}} and Raquel) for [[spoiler:the mission to rescue Violet from Granny Goodness.]]

** When [[spoiler:Razer]] is being provoked by Metron, he warns the New God "[[Comicbook/TheIncredibleHulk You won't like me when I'm angry]]."

* CorruptedContingency: The Team enters the Phantom Zone to [[spoiler:rescue Superboy who has been trapped there for months]] but are ambushed and defeated by the criminal Kryptonians that reside there. Planning for this, Nightwing breaks out a piece of kryptonite to weaken them, but being in the Phantom zone means it doesn't affect them physically and it gets taken by Dru-Zod, the Kryptonian leader. Later Dru-Zod uses the same piece of kryptonite to incapacitate Superman once they get out of the Phantom Zone.

*** Another Star Trek reference is noted with the clone of Roy Harper that went by Red Arrow choosing to [[Series/StarTrekTheNextGeneration differentiate himself using his middle name as his legal name]].
